How much yeast is in my jar?

Hi All,

I've harvested and washed some from my last batch.

Now I've been reading about yeast pitching rates and the bit that is most unclear to me is 'how do I know how much yeast I have in my jar'?

Any insight much appreciated!

Thanks,
JT

 

Probably at least enough for one, if not two, 5-gallon batches of 1.060 or less beer, but without a picture, it's hard to say.

 

Rule of thumb is the settled yeast slurry at the bottom is about 1 billion cells per mililiter. So if you have 100 mL of the settled slurry, you have 100 billion cells.
